ICON Stage 4 Coilover Conversion System for 2017-2022 Ford F-250/F-350

The ICON Stage 4 Coilover Conversion System is a bolt-in front and rear suspension upgrade for 2017-2022 Ford F-250 and F-350 4WD trucks (excluding Cab and Chassis models), delivering 2.5-3.75 inches of front lift depending on model year and trim, through a five-component kit built around ICON's 2.5 VS Series remote reservoir coilovers with Continuous Damping Control Valve (CDCV) technology, Eibach coil springs, and FK Rod End bearings.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Coilover Conversion With Ride Height Adjustment

Replacing the factory strut with a 2.5-inch remote reservoir coilover allows the front suspension to be tuned for damping and ride height independently. The coilover mounts in the OEM coil bucket location (no cutting or fabrication required), and the threaded body lets the driver dial in lift height within the available range rather than accepting a fixed ride height. For buyers who want additional front damping capacity, secondary shock provisions are built into the design; contact ICON for compatible options.

Vehicle-Specific Valving and Fully Serviceable Construction

ICON's CDCV valving is calibrated for the F-250/F-350's weight and suspension geometry, which means the damping curve is matched to the truck rather than adapted from a lighter-duty platform. The CAD-plated coilover body and 7/8-inch shaft resist corrosion, and the anodized aluminum rear shock bodies do the same at the rear. Every shock in the kit is fully rebuildable and re-valveable, so the system can be refreshed or retuned without replacing the entire unit. Eibach springs carry a lifetime guarantee against sagging or breakage.

Complete Front-to-Rear System

The Stage 4 kit ships as five matched components: the front 2.5 VS remote reservoir CDCV coilover conversion kit with cam bolts (61720C), an adjustable track bar (64038), a dual stabilizer kit (65000), two 2.0 VS internal reservoir stabilizers for dual-opposing configuration (36511 x2), and a rear 2.5 VS piggyback CDCV shock pair (37705CP). Addressing front lift, rear damping, steering stability, and alignment correction together avoids the mismatched geometry that results from upgrading components individually.

Features

• Bolt-in front fitment: mounts in OEM coil bucket location; coil centering cup removal required
• CDCV technology: Continuous Damping Control Valve valving on front coilovers and rear shocks
• Eibach coil springs: lifetime guarantee against sagging or breakage; rated for diesel engines
• FK Rod End bearings: extended longevity and minimal deflection at the coilover mounting points
• Corrosion-resistant construction: CAD-plated coilover body with 7/8-inch shaft; anodized aluminum rear shock bodies
• Fully rebuildable: all shocks can be rebuilt or re-valved without replacing the unit

Specifications

Who This Is For and Isn't

This system suits 2017-2022 Ford F-250 and F-350 4WD owners running diesel engines who want a bolt-in front coilover conversion with ride height adjustability, improved on- and off-road damping, and a matched rear shock upgrade in a single kit.

This kit does not fit F-350 or F-450 Cab and Chassis models, 2WD trucks, or gasoline-engine applications (springs are rated for diesel only). OEM wheels and 35x12.50-inch tires fit without modification; larger tires may require fender trimming. A brake line kit (Part 61111) is optional but not included. ADAS recalibration is required after installation and is not included. California residents: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm (Proposition 65).

Common Questions

Does this kit fit both F-250 and F-350 trucks?

The ICON Stage 4 Coilover Conversion System fits 2017-2022 Ford F-250 and F-350 trucks with 4WD drivetrains. F-350 and F-450 Cab and Chassis models are excluded. The system does not fit 2WD configurations.

How much lift does this system provide?

Front lift range depends on model year and trim. 2017-2019 Super Duty trucks gain 2.5-3 inches over stock. 2020-2022 trucks without the Tremor package gain 3.25-3.75 inches. 2020-2022 trucks with the Tremor package gain 2.25-2.75 inches. Rear shocks are compatible with 0-3 inches of rear lift over stock.

Are the springs compatible with gasoline-engine F-250/F-350 trucks?

No. The Eibach coil springs included in this Stage 4 kit are rated for diesel engines only. Gasoline-engine F-250 and F-350 owners should not use this system without confirming spring compatibility with ICON directly.

What does installation require beyond the kit itself?

Installation requires removal of the coil centering cup in the factory coil bucket. Advanced Driver Assistance Systems (ADAS) must be recalibrated after the install. A brake line kit (ICON Part 61111) is optional for buyers who prefer not to bend factory steel lines; it is not included in the Stage 4 kit.

Can the shocks be rebuilt or retuned later?

All shocks in the ICON Stage 4 kit are fully rebuildable and re-valveable. The coilover conversion design allows the damping to be refreshed or retuned without replacing the entire unit. Secondary shock provisions are available for the front; contact ICON for compatible options.
